Abstract in Portuguese
Este trabalho analisa a influência de mecanismos de segurança, incluindo autenticação de assinante, confidencialidade e integridade de dados, sobre o desempenho do sistema celular de terceira geração Universal Mobile Communication System (UMTS). Em função do serviço e do tamanho das chaves utilizadas foram medidos, através de simulação, o nível de potência gasto pelos equipamentos de usuário (UE) e o tempo de resposta em aplicações do tipo Web. Verificou-se que os efeitos negativos produzidos pelos mecanismos de segurança são pequenos em relação à proteção maior que é obtida nos sistemas UMTS Terrestrial Radio Access Network (UTRAN) e Core Network (CN).

Abstract in English
This work is aimed at analyzing the influence of security mechanisms, including user authentication, data confidentiality and integrity, related to system cellular performance of third generation named Universal Mobile Telecommunication System (UMTS). By the service and the size of the used keys, there has been measured through simulation, the power level spent by the user equipments and the response time at web applications usage. It is seen that negative results produced by security mechanisms are small related to the greater protection that is get on UMTS Terrestrial Radio Access Network (UTRAN) systems and Core Network (CN).
